Why is the importance changed from Critical to High? I am experiencing
3-5 crashes per day and am not aware of any workaround. This is more or
less an unusable system and I am seriously thinking of downgrading
again.
Johan Tol, have you tried to get a backtrace like I mentioned in #8?
That way it
Yes. All are dated after the update to 15.10.
_usr_bin_akonadi_akonotes_resource.1000.crash,
_usr_bin_akonadi_archivemail_agent.1000.crash,
_usr_bin_akonadi_archivemail_agent.1000.upload,
_usr_bin_akonadi_archivemail_agent.1000.uploaded,
_usr_bin_akonadi_ical_resource.1000.crash,
I'm not sure what you mean with "kernel call trace".
The first entry in syslog which is related to the crash mentioned in #13 is
Nov 1 12:53:06 gondor org.a11y.atspi.Registry[4315]: XIO: fatal IO error 11
(Resource temporarily unavailable) on X server
":0"
But this is not always the same.
I already had two crashes today, but no specific xorg file. One of the crashes
happened at 12:53:06 according to syslog. Only one file in /var/crash, namely
_usr_bin_akonadi_maildispatcher_agent.1000.crash is related to that crash and
occurred at 12:53:08 according to the crash file.
Sorry, now I know what you mean: log messages from #3.
These appear at completely different times, so probably they are unrelated to
the crashes (see again syslog in #2). I mentioned them because they also
involve the intel graphics, so who knows...

Concerning 14.04, I think the bug was not present there, but I'm not sure (see

Kernel versions =3.17 do include the patch, so with Ubuntu 15.04 latest, the
bug will be gone. But hopefully, the patch will be included already in updates
for 14.10.

Hi Bernhard,
yes, this is how it should be done. You can store the patch-file in the
